DreamWorks Animation Turns to Technology for
Production Support
  • Problem Gaining an edge in an intensely
    competitive market, working with
    technology-intensive processes.
  • Solutions Deploy custom-built E-motion software
    to render more realistic animations and increase
    quality of films.
  • HP processors, Linux, and high-speed network
    facilitate rapid production schedule, increasing
    productivity.
  • Demonstrates ITs role in strengthening a firms
    product and productivity beyond what human talent
    can accomplish.

The Capacity of Hard Disk Drives Grows
Exponentially 1980-2007
From 1980 to 1990, hard disk drive capacities for
PCs grew at the rate of 25 percent annual
compound growth, but after 1990, growth
accelerated to more than 65 percent each year.

Software Platform Trends and Emerging Technologies
Is It Time for Open-Source?
  • Read the Interactive Session Technology, and
    then discuss the following questions
  • What problems do Linux and other open-source
    software address? How does open-source software
    help solve these problems?
  • What issues and challenges do open-source
    software present? What can be done to address
    these issues?
  • What are the business as well as the technology
    issues that should be addressed when deciding
    whether to use open-source software?

Application Service Providers Two Tales
  • Read the Interactive Session Technology, and
    then discuss the following questions
  • Compare Thermoss experience with an application
    software provider with the experience of
    ResortCom.
  • Why do you think Thermos had an easier time with
    a hosted software service than ResortCom? What
    management, organization, and technology factors
    account for this difference?
  • If your company was considering using an
    application service provider, what management,
    organization, and technology factors should be
    addressed when making your decision?
